There is a whole lot of these folks on the Rudy threads. I ask them over and over and over again: "If your guy wins the nomination I will vote for him. If Rudy is the nominee will you vote for him?"
They either do not answer or say stay home or third party, how nice.
I think that is s good reason to ignore them then and not count on them at all. If they come to their senses - fine - if not - we have already planned for them to play martyr and punisher.
